SASH-SUPPORTER.

SPECIFICATION forming part of Letters Patent No. 230,238, dated July 20,1880.

Application filed November 13, 1879.

To all whom it may concern:

Be it known that I, JEssE CHANDLER, of Warsaw, in the county of Hancockand State of Illinois, have invented certain new and useful Improvementsin Window Lock and Sash-Support; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and to.letters of reference marked thereon, which form a part of thisspecification. I

My invention relates to an improvement in sash-supporters, the objectbeing to provide a self-acting device for supporting the sash at anydesired adjustment; and to that end the invention consists in certaindetails of construction and combinations of parts, as will hereinafterbe described, and pointed out in the claims.

In the accompanying drawings,-Figure l is a side elevation of awindow-sash having my improved sash-support attached thereto. Fig. 2 isan enlarged view of the device, and Fig. 3 is a detached view of one ofthe metal supporting-blocks.

A is a self-acting dog or gravity-catch pivoted to the upperwindow-sash, as at a, whereby it is allowed to swing freely toward andfrom the window-frame B. The gravity catch or dog A is constructed witha lateral projection, I), havinga beveled upper edge, 0, while the rearend is furnished with an angular projection, (I, the latter serving as athumb and finger piece for moving the catch.

Any desired number of metal blocks 0 are secured to the window-frame,according to the varied adjustment that may be desired to be given thewindow sash. These blocks are formed with projections e on their rearsides, which projections enterthe woodof the windowframe as the block isscrewed snugly against its seat, whereby the blocks are prevented fromrotary displacement and all undue strain in the fasteningscrewsobviated.

One of.the supporting-blocks G is secured to the frame of the window ata point below the top of the lower sash, for a purpose hereinafterexplained.

D is a guard placed around the self-acting catch or dog A, in order toprevent the latter from being tampered with from the outside when thecatch A is lowered below the top of the lower sash, the top rail of thelatter being grooved to permit the passage of the guard.

The sash may be lowered by simply forcing the catch or dog A laterallyaway from its supporting-block, when it will by its gravity fall backand catch on the supporting-block.

When the sash is raised .the catch or dog A is automatically thrownoutward or away from the supporting-block by reason of its beveled orinclined edge striking its under side of the block, thus forcing thecatch away from the same and allowing it to be raised and adjustedWithout adjusting the catch or dog.

Guard D is constructed with upper and lower flanges, g y, and sideflange, Z), said flanges projecting outwardly from the window-sash,while the side i of the guard, located adjacent to the window-frame, isleft open. The gravity dog or catch A is pivoted and adapted to swingwithin the guard.

When the window-sash is in its raised position the gravity-dog may bereadily actuated; but when lowered so that the guard is below the lowersash the guard prevents access being had to the gravity dog or catch.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination, with the metal blocks 0, attached to the window-frame,of a gravity catch or dog, A, and a guard, D, the latter constructedwith upper and lower flanges, g g, and side flange, b, the side 'i beingformed without a flange, and the catch or dog pivoted within saidguard-flanges, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this3d day of November, 187 9.

JESSE CHANDLER.
